Re: Dipole moments

A molecule will always be covalent because it is covalently bonded. The dipole moment determines whether the covalent bond has ionic or covalent character because of the charge difference. If there is a dipole moment, it is a polar covalent bond, and as a result of the partial positive and partial ...

Re: Elements having octets

Okay, so CNOF are always octets since they do not have a d orbital, but those that have d orbitals (periods 3+) can have more if their formal charge allows for it?

I am still slightly confused on how some elements can over an octet, while we also automatically assume some elements have octets no matter what. Can someone clarify for me?

For calculations I would just keep the entire number on the calculator but round the numbers when I write them down. Just make sure that the final answer is in sig figs. This seems like it makes the most sense.
